METHOD OF GENERATING ARTIFICIAL HEAT.

SPECIFICATION formingpart of Letters Patent No. 234,190, dated November9, 1880.

Application filed April 7, 1880.

To all whom it may concern Be it known that I, BENJAMIN N. HUEsrIs, ofPhelpstown, in the county of Putnam and State of New York, have inventeda new and useful Improvement in the Art of Generating Heat, of which thefollowing is a specification.

The invention relates to an improvementin the art of generating heat;and it consists in burning petroleum, either crude or refined, over orin connection with a bed of calcium or of common lump-lime.

The invention is not limited in its application to any particular formof apparatus, it being only necessary that the usual boiler. fire-box,and a blower be employed. It will be found essential to provide theblower with a cock, by which the supply of oil may be regulated, andgenerally to observe the steps which are customary in burning petroleum.

In operation, the boiler being filled with water, asufficient quantityof broken lime is placed in the fire-box to cover its bottom, and enoughoil then run in to saturate the same. To ignite this I take a smallpiece of lime, and, after wetting it with oil, light it with a match andapply it to the furnace. The blower is then turned on, the supply of oilbeing regulated according to the size of the furnace. The quantity oflime employed will depend upon the size of the fire-box. It is desirablethat enough be used to form a thick bed, al-

(No model.)

though a good result will be effected when even a small quantity isemployed.

The nature of the invention having been explained, convenient anddesirable methods of practicing it will at once suggest themselves topersons skilled in the art to which it has relation.

As I conceive that I am the discoverer of the fact that calcium andpetroleum may be burned in conjunction with enhanced results, I do notlimit my claim to quantities or proportions; but

What I do claim, and desire to secure by Letters Patent, is-

l. The process of generating heat, consisting in burning crude orrefined petroleum in connection with calcium or with common lumplime, asset forth.

2. The process of generating heat, consisting in burning petroleum inconnection with a bed of calcium or of common lump-lime saturated withthe oil, as specified.

In testimony that I claim the foregoing improvement in the art ofgenerating artificial heat, as above described, I have hereunto set myhand this 2d day of February, 1880.
